"The global demand for energy continues to grow. Amid ongoing geopolitical events, many nations seek energy security for economic development and population growth. Oil and gas will remain key components of the global energy mix as the

transition to a lower-carbon future moves forward."

Letter from the CEO

As global energy demand rises, oil and gas remain crucial for nations focused on energy security and economic growth. At Noble, we strive to support our customers to deliver safe and reliable energy while supporting their decarbonization efforts.

I am pleased to share our progress and achievements in this 2024 Sustainability Report, which covers metrics, strategic focus areas, and initiatives for our environmental, social, and governance performance.

For Noble, 2024 was a year of leaning in and valuing insights from our customers and stakeholders, which shaped our actions. At the same time, we remained focused on our sustainability framework consisting of our pillars: Sustainable Energy Future, Caring for People and Responsible Business. Our learnings are driving our short-, medium-, and long-term planning to advance these pillars.

A significant milestone in 2024 was our acquisition of Diamond Offshore. Our fleet is now unified under one umbrella, further enabling our continued growth.

Noble's dedication to a Sustainable Energy Future drives our goal to reduce carbon intensity by 20% by 2030 from a 2021 baseline. We have made great progress

so far and are assessing the impact of our expanded fleet on this target, while continuing our collaboration with customers and rig crews to find additional ways to reduce our rigs' carbon footprint. Programs like our Energy Efficiency Insights for rig crews and innovations in carbon capture and storage are proving to have great potential.

At Noble, our dedication to health and safety is paramount. In 2024, we launched the Potential Consequence Severity Index across our fleet to proactively address safety issues. The intent is to drive a proactive approach to safety, focusing on improving our safeguards offshore and expanding our capacity to carry out our operations safely.

People remain our most important asset, and programs like our global Subsea Training Program and scholarships for marine cadets in Guyana demonstrate our constant focus on caring for people. Continuing our century-long legacy, we aspire to being the First Choice for our employees.

By focusing on and investing in safe, reliable, and efficient operations, we secure our future and aim to become the First Choice OffshoreSM. I am grateful for the dedication of our employees, the support of our Board of Directors, the trust of our shareholders, and collaboration with our customers.

Thank you for taking the time to learn about Noble's sustainability framework and progress. We welcome your feedback to help us plan our future reporting.
